Description

Wingspan: 32 - 46mm; Length: 33 - 38mm

The male Variable Damselfly has broken antehumeral stripes (sometimes they are missing entirely), a thick black wine goblet shape on S2, and S9 is more than half black. Females occur in two colour forms, dark and blue.

It has a patchy distribution in Britain, being mainly found in Somerset, Sussex, Kent, the Norfolk Broads, the Fens, Anglesey and south Galloway. It is widely distributed in Ireland.

This species needs well-vegetated grazing-marsh ditches, fens, ponds, lakes and canals.

Eggs are laid into the stems and leaves of aquatic plants. They hatch after a month, and the nymphs probably take a year to mature.

Most aspects of behaviour are similar to the Azure Damselfly. Adults are often found in lush vegetation away from the water's edge.

This is a Red data list species in Britain.
